Technology Factors Influencing the Adoption of Shrimp Farming

Commercial shrimp Culture has emerged as one of the most important sectors of the aquaculture industry in India: The cultured shrimps in the coimtry alone contribute to 50 per cent of the total shrimp exports from India. Much of this phenomenal successs has been attributed to the production and dissemination of a host of improved technologies starting from pond preparation till harvest of the cultured shrimps. The existing knowledge structure of the farmers is further enhanced when they are exposed to more scientific farming technologies containing more attributes of the innovation which influence their adoption process. It is frequently asserted that as farrriers gain in experience or obtain more accurate and scientific knowledge, their capacity to manage shrimp ponds in a more sustainable way is enhanced. (Saengnore and Lebel, 2002). The technology adopted ranges from traditional to improved, traditional within the coastal regulation zone and extensive shrimp farming outside the coastal regulation zone (Anon. 2002)

Perceptions of rubber growers on information technology enabled rubber export system

The Expert system for plant protection of rubber was developed using Visual Basic 6. O. The computer based Rubber Expert System thus developed was abbreviated as RUBEX-04. Perceptions of Rubber Growers on Information Technology enabled Rubber Expert System was studied. It was evident that, majority of the respondents (60.83 per cent) were found to have high level of perception about modern information communication technologies, followed by 21.67 per cent with medium and remaining 17.50 per cent with low level of perception of modern information and communication technologies. It could be exonerated from the study that slightly less than three-fourth of the respondents reported that they were most satisfied with the diagnostic path which was sequential and logic in RUBEXS-04. A majority (81.67 per cent) of the respondents were most satisfied about the correct conclusion provided by the RUBEXS-04. More than half of the respondents were most satisfied that, photographs helped them to confirm the incidence of disease and pests. Most of the subjects preferred the Expert System for other technologies of rubber like, latex preservation and processing, tapping and yield stimulation and soil management, in addition to RUBEXS-04

Monitoring edge-geodetic sets in graphs

We introduce a new graph-theoretic concept in the area of network monitoring. In this area, one wishes to monitor the vertices and/or the edges of a network (viewed as a graph) in order to detect and prevent failures. Inspired by two notions studied in the literature (edge-geodetic sets and distance-edge-monitoring sets), we define the notion of a monitoring edge-geodetic set (MEG-set for short) of a graph $G$ as an edge-geodetic set $S\subseteq V(G)$ of $G$ (that is, every edge of $G$ lies on some shortest path between two vertices of $S$) with the additional property that for every edge $e$ of $G$, there is a vertex pair $x, y$ of $S$ such that $e$ lies on \emph{all} shortest paths between $x$ and $y$. The motivation is that, if some edge $e$ is removed from the network (for example if it ceases to function), the monitoring probes $x$ and $y$ will detect the failure since the distance between them will increase. We explore the notion of MEG-sets by deriving the minimum size of a MEG-set for some basic graph classes (trees, cycles, unicyclic graphs, complete graphs, grids, hypercubes,...) and we prove an upper bound using the feedback edge set of the graph

Effectiveness of expert system on knowledge retention

Artificial intelligence based computer programmes called Expert System has received a great deal of attention throughout the world, due to its impressive problem solving capability in a variety of fields. For the present study, an expert system named as RUBEXS-04 was designed to simulate the pest and disease diagnosing behaviour

Perception of attributes of shrimp farming technologies by shrimp farmers

During the last decade, shrimp aquaculture has become a major sector of fish farming in terms of space occupied and of inarket value. In India, commercial shrimp farming ,tan ed gaining roots oflly during the mid eighties. The boom period of commercial scale shrimp culture in India started in 1990 and the bust came in 1995-96, with the outbreak of viral disease

Relationship between profile characteristics and knowledge gained

Indian Agriculture has made impressive strides in the development of new plant varieties, cultivars; hybrids and production and standardization of plant protection techniques

Information utilization behaviour and constraint analysis among shrimp farmers

Information utilization behaviour and constraint analysis among 60 selected Slzrimp farmers of Nellore district of Andhra Pradesh was studied. The findings of the study revealed that private consultants followed by feed technicians were the most important sources of information utilized by 76.67 per cent and 71.67 per cent of Shrimp farmers. Among constraints, disease incidence, poor quality of seeds and lack of quality control agencies were expressed by 81.67, 63.33 and 65.00 per cent of the respondents. Among the suggestions offered by the Shrimp farmers, setting up of disease diagnostic centers, seed certifying agencies and quality con trol agencies for regulating the quality of chemicals accoreded top priority

Involvement of extension personnel in implementing social forestry programmes

In a country like India, where the population is high and resources are limited, social forestry is an instrument for rural development, particularly for the poor people. Thus social forestry is identified as a forestry of the people, by the people and for the people

A study on the knowledge gain related to skills, knowledge retention and symbolic adoption using expert system among rubber growers

Artificial intelligence based computer programmes called Expert System has received a great deal of attention throughout the world, due to its impressive problem solving capability in a variety of fields. For the present study, an Expert system RUBEXS-04 was designed to simulate the pest and disease diagnosing behaviour of human expert in rubber trees
